Will it behave like a bonded contact attached to the point mass?

Hi

Yes, something like that you could say.

See below for an explanation on how it is implemented in the background (so what is sent in the form of a ds.dat input file from Mechanical to the solver).

Thanks for the reply ekostson.
What is the difference between coupled, rigid and deformable options for point mass? If I would like to attach a rigid body as a point mass to a flexible bracket with geometry scoped at the mounting holes for the bracket, which behavior is appropriate?
Thanks in advance.

Search the help manual and the internet there are many discussions on this topic, e.g.,
Choose then the one that you think might represent the real situation best. If none does then model the component as it is, so without any approximations (point mass).

All the best
